FEEDING EXPERIMENTS WITH ISOLATED FOOD-SUBSTANCES. 



THE CHARTS AND THEIR EXPLANATIONS. 



In the following charts, to which reference is made in various 

 places in the text, the abscissae of the curves represent days and the 

 ordinates actual body- weight (solid line) or food-intake (dotted line) 

 in grams. In some of the charts the average (normal) curve of 

 growth, plotted from body- weight data available for normally grow- 

 ing animals of the same sex, is represented by a broken line for com- 

 parison. The food-intake curve is plotted from the quantities of food 

 eaten per week. The numbers on the body-weight curves indicate 

 the time at which changes in the character of the feeding were insti- 

 tuted. All curves in this paper are plotted on the same scale, so that 

 they are directly comparable.
